ELECTRIC-LAMP-SOCKET SUPPORT.

Specification .of Letters Patent.

Patented July 5, 1910.

Application filed January 13, 1910. Serial No. 537,910.

To all whom. it may concern:

lie it known that I, HERBERT E. Puss, a citizen of the United States of America, residing; in the city of Newark, county of Es sex. and State of New Jersey, have invented a certain new and useful Improvement in lllectric-Lanip-Socket; Supports, of which the t'ollowing is a specification.

The object of my invention is to construct a support for electric lamp sockets especially adapted for use in lamps for automobiles amt other vehicles, so that. on the one hand, ditl'ercnt' sizes of lamps may be used as occasion may require, and so that, on the other hand, the liability to breakage of the lilanients by the shocks and jars of the moving vehicle shall be minimized. This object I attain by the construction which I will now describe.

in the accompanying drawing, Figure l is a side elevation ot'iny lamp socket support showing a small lamp in position; Fig. 2 is an elevation looking atv the suppprt from the other side and with a larger lamp in position; Fig. 3 is an end view of the socket support without any lamp; Fig. 4: is a plan View of the bracket alone.

My improved lamp socket support is especially intended for use in lamps of autoqnobiles and other vehicles and has been designed for application to the caps of oil lamps or the gas pillars of acetylene lamps, so that when it is desired. to use an electric lamp instead of the oil or gas lamp, the electric lamp may be quickly inserted and attached, and no matter what the size of lamp used, it may be readily brought. into proper focus with relation to the reflector. of the head-ii ght.

In Fig. 1-1 have indicated by dotted lines at A the cap of an oil lamp, and to tit over this. cap I provide the supporting bracket 13 with a more or less flexible me'allic strap 1) to embrace the cap of the oil lamp. A smaller strap will be used for the gas pillar. An adjustable couplin} screw b permits the strap to cap after it: has been titted over it. The bracket arm ll will then stand horizontally, and upon this I fit. an insulated sleevel) with a set. screw (1, Figs. 1 and 3, by which the sleeve D may be secured to the arm B when it. has been adjusted to proper position thereon. 'lhis insulated sleeve, D supports the electric lamp socket. through the be tightened around the lamp medium of a coiled spring or springs E. I prefer to use two of these springs, E, E, side by side. The lower ends of these springs are permanentlysecured to the top of the sleeve and \to the upper ends'of the sprnils'lpermanently secure the plate F. livoted to this plate F by a securing screw and nut. f is the internally threaded lamp socket G to receive the .base of the lamp L.

Secured to the plate F .,but insulated therefrom is a contact spring H with which the central contact of the lamp base will make connection when the lamp is screwed into the socket. One circuit wire is secured .to the binding post h in electrical contact with the spring H, while the other circuit Wire may be secured under the binding screw cl to make connection through the metallic socket piece G with the screw shell terminal of the lamp base. ly means of this pivotal connection at the lamp L may be turned into position For use, asshown by tull lines in Fig. ;l,'or may be turned to a position out, of the way of the oil lamp when the latter is to be used, as indicated by dotted lines in Fig. 1. If a larger size of electric lamp than that shown in Fig. 1, for example, is required, the sleeve D is moved outwardly on the arm B and secured in its adjusted position by the screw (Z, as indicated for example in Fig. 2, and as the proper focus-- ing of the lamp may require. It will be seen thatthe interposition of the springs I") will reduce to a minimum the liability to breakage of the filaments of the electric lam by the shocks and jars of the traveling vehicle. And since the lamp when in use will stand in the inclined position indicated in Figs. 1 and 2, it is an advantage to use two springs E, E, having their axes in a. vertical plane passing through the axes of the socket and lamp.

I claim as. my invention: 1. The herein described electric lamp socket support, comprising a, bracket; and means secured thereto to support a lamp socket with an interposed spring with its lower end secured to a part on the bracket, and at itsupperjend to a partontho socket, said spring constituting the mechanical support, for the latter, as and for the purpose set forth.

2. The herein described electric lamp socket,- support, comprising a bracket and means secured thereto to support the socket,

- set forth.

in combination with the socket and two in- A terposed springs secured at their innerends side by side to a part on the bracket, and at their upper ends to a part on the socket, said spring constituting the mechanical support for the latter, as and for the purpose 3. The herein described electric lamp 1 socket support, comprising a bracket, a

sleeve adjustable thereon, a spring secured at its lower end to the sleeve, a plate carried by the upper end of the spring, and a socket 4. The herein describe pivotally connected to the late. 7

electric lamp socket support, comprising a bracket, a sleeve horizontally adplstable 011 the bracket,

a pair of springs secured at their lower ends side by side tothe sleeve, a plate carried by the up er ends of the springs and a socket.

pivotal y connected to the plate.

5. The herein described electric lamp 5 socket support for automobile lamps, comprising a bracket having means whereby it i I may be secured to the ordinary oil or gas lamp, supporting means adjustable on the bracket toward or from the oil or gas lamp, and an electric lamp socket pivoted on the supporting means as and for the purpose described.

6. The herein described electric lamp socket support for automobile lamps, comprising a bracket having means whereby it may be secured to the-ordinary oil or gas lamp, an electric lamp socket, a support to which the latter is pivoted to throw the lampinto and out of focus and spring means carrying the electric lamp support on the' bracket.
